Title: Method and device for displaying three-dimensional digital data by tensol rendering
Inventor: NAGASAWA MIKIO
IPC: G06T15/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To visibly display spatial distribution of multi-valued functions represented by nine components of a two-stage three-dimensional tensor. SOLUTION: The distribution function 101 of anisotropic fine face distribution 102 corresponding to the surface of discrete sample points 103 having tensor quantity is expressed by the secondary curved surface shape of an anisotropic ellipse and the intensity of scattered light is calculated from the contribution of a bisector direction 107 between a light source direction 105 and a visual line direction 106 to simulate the scattering of light. The intensity of scattered light on each calculation point having tensor quantity is integrated by the beam equation of rendering by weighting the transmission factor of light.  Since correlation between the integration effect and angular dependency of light based on a scatter distribution function corresponding to tensor components is displayed, multi-valued information in space can be visually recognized without requiring pattern recognition or the like.

Title: Three-dimensional measuring device
Inventor: ECHIZENYA TATSUO
IPC: G01B21/00
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To perform three-dimensional measurement accurately. SOLUTION: When a measuring point is subject to measurement, the contact pressure of a measuring probe 14 is detected by a torque sensor 20. When the obtained value is judged to be larger than a reference pressure value by a judging part 32 of contact pressure, the contact angle of the probe 14 is changed within such a range where an interference checking part 28 judges it to have no interference, and the measuring point is measured again. When the obtained value still exceeds the reference pressure value, the approaching speed of the probe 14 to an object to be measured is made low by a measuring speed control part 34. Thus, even when the object has a small rigidity, it can be measured accurately.
